  An ECC domain parameter; the cofactor, a positive integer that is equal to the order of the elliptic curve group, divided by the order of the cyclic subgroup generated by the distinguished point G. That is, nh is the order of the elliptic curve, where n is the order of the cyclic subgroup generated by the distinguished point G.
